I can't do it justice with an excerpt, so go read the whole thing. I actually don't have any strong feelings either way, but I'm sufficiently fascinated by the topic that I want to hear more about the debate. More info on leap seconds can be found here, and an overview of the problem and the proposed US solution is here.

My favorite bit from the whole article:

Ending leap seconds would make the sun start rising later and later by the clock -- a few seconds later each decade. To compensate, the U.S. has proposed adding in a "leap hour" every 500 to 600 years, which also accounts for the fact that the Earth's rotation is expected to slow down even further. That would be no more disruptive than the annual switch to daylight-saving time, said Ronald Beard of the Naval Research Laboratory, who chairs the ITU's special committee on leap seconds and favors their abolishment. "It's not like someone's going to be going to school at four in the afternoon or something," he said.

If only we could put off all of our problems for another 500 years! Of course, since this is likely to cause a Y2K-style panic in many places when it happens, perhaps we ought to cryogenically freeze a few COBOL programmers before we implement this, so that when the problem appears on the horizon we'll have some people with previous experience in dealing with it.
